UNITED STATES PATENT OFFIC JOHl\ BEAVOR JVEBB, OF NEIV YORK, N. Y.,ASSIGNOR TO ALEXANDER J. LEITH, OF SAME PLACE.

YOKE-FRAME FOR CABLE ROADS.

SPECIFICATION forming part of Letters Patent No. 394,801, dated December18, 1888.

Applicatiofi filed July 10, 1888.

To all whom it ntay concern:

Be it known that I, J OHN BEAvoR-WEBB, a citizen of Great Britain, and aresident of New York city, county, and State, have invented a new anduseful Improvement in Yoke- Frames for Cable Roads, of which thefollowing is a full, true, and exact description, reference being had tothe accompanying drawings.

My invention relates to a pressed-steel flange yoke-frame made in onepiece and arranged to support the rails and to carry the cable and cablemechanism in a chamber provided therefor, and which may likewise beprovided with an openingor openings, through which electric conductorsor otherbodies may extend.

The present yoke frames generally employed are made of a number ofpieces bolted together, which are liable to become loosened or detached,and which are, at the best, expensive and insecure. In some cases castiron yokeframes have been made, which, however, are liable to breakunder the jar of travel, and consequently have to be supported byvarious devices.

By my invention the castiron sometimes employed is dispensed with andthe yokeframe itself is stamped from a single piece of wrought-steel.The flanges project upon one side, and'when the yoke-frame is set in theground they form an important function in holding the yoke frame in theground, the earth or other filling surrounding and pressing into thespaces between the flanges.

My invention will be readily understood from the accompanying drawings,in which Figure 1 represents a vertical elevation .partly in section;and Fig. 2, a central vertical section through Fig. l, partly inperspective.

The yokeframe itself is preferably of approximately the shape shown; andconsists, generally, of the two arms H H, extending laterally andsupporting the rails R R, and two central supporting parts, K K, uponwhich the slot-irons E E are supported, and of a central opening, G,through which the cable channel or tube passes.

The yoke-frame is arranged with an upper flange, B, and a lower flange,O, and also with internal flanges, D, surrounding the openings SerialNo. 279,529x (N0 model.)

F, arranged for the reception of electric wires or other bodies. Theseinternal flanges, D, both assist in strengthening that part of theyoke-frame and also co-operate in holding the yoke-frame firmly in theground when packed in position. The rails R and slotirons E may bebolted to the yoke-frame or secured in any other suitable manner, theflange B serving as a support and rest, upon which they may be securelyfastened. It is obvious that I may add one or more additional openingsto this, as shown-as, for instance, an opening in the bottom of theyoke-frame, if desired. It is obvious, likewise, that, though the flangeis shown as continuous around the external edge of the yoke-frame, andthough that is the best construction, a part of it may be omittedwithout losing altogether the benefits of my invention.

Vhat I claim as my invention, and d esire to secure by Letters Patent,is

1. A pressed-steel flanged yoke-frame for cable roads, having acontinuous flange integral therewith and surrounding its exterior edgeand likewise the cable-opening, substantially as described.

2. A pressed-steel flanged yoke-frame for cable roads, made in one pieceand having the flanges QB integral therewith, substantially asdescribed.

3. The pressed-steel flanged yoke-frame for cable roads, made of onepiece, having the flange B C, the arms H H, and intermediate supports, KK, substantially as described.

4:. The pressed-steel flanged yoke-frame for cable roads, consisting ofa flanged steel plate having the arms H H, the supports K K, and theopenings F F, substantially as described.

5. The pressed-steel flanged yoke-frame for cable roads, made of onepiece, having the flange B C, the arms H H, the rails R R, supportedthereon, the intermediate supports, K K, and the slot-irons E E,supported thereon, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
